The solitaire puzzle series Brains is now a competitive game for up to four puzzle enthusiasts. In Brains Family: Burgen & Drachen, players compete to fight powerful dragons and reach fabulous castles. At the start of each round, someone reveals an adventure card that shows the locations of dragons and castles on the boards. Then all players race to be the first to place their tiles on their individual player boards so that their knight figure travels to all the castles. Whoever finds the right answer wins the round. Initially fighting against the dragon is optional, but once a player has won a round, they must fight the dragon in each subsequent round, in addition to visiting all of the castles. Whoever wins three rounds first wins the game.
